Application iiled I'ehlnary 24, 1902. Serial No. 95,235- (No model.)

To all whom it may concern.-

Be it known that I, JosErn Il. WILLIAMS, a citizen of the United States,residing at Upper Alton, in the county ot' Madison and State ofIllinois, have invented a certain new and useful Locomotive-Boiler, ofwhich the following is such a full, clear, and exact description as willenable any one skilled in the art to which it appertains to make and usethe same, refro erence being had to the accompanying drawings, formingpart of this specification.

My invention relates to improvements in Water-tube boilers forlocomotives.

The object of my invention is to improve i5 the construction of suchboilers, so that the circulation of the water will be improved and sothat the boiler can be readily cleaned.

My invention consists ina boiler for locomotives and the like,consistingI of an inner 2o shell, an outer shell, horizontal Water-tubespassing through said inner shell, and vertical water-tubes passingthrough said inner shell and through said horizontal tubes.

In the accompanying drawings, which show z5 so much-fof a locomotive asis necessary to illustrati-:g one form of my invention, Figure 1 is avertical longitudinal section of the boiler; and Figs. 2 and 3 aresections on the lines 7 7 and S 8, respectively, of Fig. 1.

Like marks of reference refer to similar parts in the several views ofthe drawings.

The boiler is composed of an outer shell 16 and an inner shell 17,arranged so as to leave a water-space between the two shells. 18represents horizontal water-tubes, which pass longitudinally through theinner shell 17. 19 represents vertical water-tubes, which pass throughthe inner shell 17 and also through the horizontal tubes 18. Theseverwhich is formed by the front part of the inouter shells and to thewater-tubes for washtical tubes 19 are provided with openings 20,opening into the horizontal tubes 18.

21 is the smoke-stack, which has its lower end secured in thecrown-sheet 22 of the inner shell 17 and opens into the smoke-box 23,

t5 ner shell 17 and forms a continuation of the combustion-chamber 24.The lower end of the com bustion-cham-ber 24: is provided with a grate25 of the usual construction, to which fuel is fed through the door 26.Above the crown-sheet 22 are arranged two longitudinal bars 2S, whichare connected by tie-bars 29. These bars 2S and 29 are connected to theouter shell 16 and the crown-sheet 22 by means of stay-bolts 30, andstaybolts 30 are also arranged between the outer and inner shells atsuitable intervals to strengthen the boiler.

31 represents screw-plugs arranged to give access to the space betweenthe inner and 6o ing out the boiler.

32 is a steam-dome, and 33 the sand-box.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

A boiler for locomotives and the like, consisting of an inner shell, anouter shell, horizontal water-tubes passing through said inner shell,and vertical water-tubes passing through said inner shell and throughsaid horizontal tubes.
